Broadband, High-Gain Directional C-Band Antenna
The SL-520A-501 is a broadband, High Gain Antenna, providing continuous communications coverage across the spectrum of 4.4 GHz to 6.0 GHz and beyond.
Its primary use is to enhance Wi-Fi network signals in 802.11a and 802.11n modes in the Americas, and in the US U-NII bands (5.150-5.350, 5.470-5.725 and 5.725-5.825 GHz). In Europe the SL-520A-501 will support 802.11h ETSI HiperLAN/1 (5.150-5.350 GHz) and HiperLAN/2 (5.470-5.725 GHz) applications simultaneously. . . and, in Asia, the very same antenna will support High Speed Wireless Access applications at 5.150-5.250 GHz.
Future applications include the Intelligent Highway (ITS = Intelligent Transport System) proposed C-V2X communications, 5.9 GHz band, and other Self-Driving vehicle to infrastructure and vehicle to vehicle communications.
The broadband nature of this Directional Antenna allows concurrent operation on all of the above services, in addition to doubling up as a Directional Antenna in C-Band Telemetry and Video applications. For example, it can be used as a portable, high gain (+9 dBil), search C-Band Antenna, to enhance the downlink video feeds (as a first person view or fpv antenna) of remote control (RC) planes and UAVs (drones), boats, cars and robots; or to connect wireless security equipment, such as cameras. It can also be used as a point to point 5 GHz Antenna for short to medium ranges.
